How does cloning relate to other reproductive technologies?
Livestock cloning is the most recent evolution of selective breeding in animal husbandry, which dates back to the dawn of time. Arab sheikhs first used artificial insemination in horses as early as the 14th century. In the last fifty years, techniques such as embryo transfer, in vitro fertilization, embryo splitting, and blastomere transfer have become commonplace – providing farmers and ranchers powerful tools for breeding their best animals. Cloning accelerates the birth of the best possible stock by allowing farmers to be certain of the genetic make-up of a particular animal. See timeline.
